Breathable structure that can be fitted to articles to be worn by persons

Abstract

This structure is noteworthy in that it consists of at least one grid ( 2 ) made from flexible material that can deform in accordance with a mesh established over its entire surface, the grid having a plurality of projecting shapes ( 2 a ) obtained by a shaping treatment giving them a shape memory, said shapes ( 2 a ) obtained in mesh form ( 2 a ) being disposed and arranged in order to define ventilation channels, and in that the peripheral walls ( 2 b ) of said shapes ( 2 a ) and their upper faces are flexible and deformable, ventilation taking place through the entire mesh of the grid.

1 . Structure providing a ventilation function and able to be fitted to any articles to be worn by persons, said structure comprising projecting zones forming stiffeners, defining channels for the passage of air and for ventilation, wherein said structure consists of at least one grid made from flexible material that can deform in accordance with a mesh established over its entire surface, the grid having a plurality of projecting shapes obtained by a shaping treatment giving them a shape memory, said shapes obtained in mesh form being disposed and arranged in order to define ventilation channels, and the peripheral walls of said shapes and their upper faces are flexible and deformable, ventilation taking place through the entire mesh of the grid.
